well the first thing that caught my eye that you said and I quote "We talk about mundane things like what we do" and I wanted to know does the interaction at this stage go into an interview style? because if it is then that is one thing you should improve. If you feel the conversation is mundane then probably she thinks the same way or atleast picking the vibes off you which is killing your rapport big time.
I do understand that such questions are boring, but they are the same questions that will get your conversation going or opens a window of opportunity for you to drop bait so it is up to you to convey them in an interesting manner and that can only come by learning to talk in general. When you learn to ramble you learn how to keep things going in a convo and I may not be the best rambler there is, but I did get better and now the conversation part is not an issue aslong as I got myself in the mood to talk. I practiced rambling by doing the following:
1-Roosh says watch an episode of Seinfeld a day as it is the perfect example of rambling.
2- I interact with anyone no matter age/sex on a daily basis, just open that old guy on the subway, chat with this girl and her dog in the park, talk to that old lady buying cat food at the store..just talk.
As for dropping bait, it comes with conversational skills, you just don't give full answers to up your mysteriousness, to get her to ask more, also you might say something along these lines:
You: Ya that bracelet reminds me of an old gypsy in Romania, that was the most weird encounter I ever had.
She: really what happened? / you went to Romania what did you do? ---> Hence rambling.
Look Bait doesn't mean baiting her and getting you pussy, it is just a way to get her engaged and increases the comfort level in the interaction it is a means to an end.
Now regarding the lack of sexual tension, think about this, if you the guy who wants to bang that girl that you asked her out, can't feel sexual tension then how should she feel it? Again vibes vibes vibes. If there is a lack of sexual tension in an interaction I'm having, it is because I didn't escalate properly, plain and simple. There's no manual to a proper escalation, it just takes practice.
Ofcourse the palm reading and all of that is
OK kino I supposed, but are you making subtle kino to make her comfortable with your touch?
A light touch on the forearm, putting your arms around her waist lightly as you maneuver through the crowd at the bar? then you sit down and have a good eye contact as you ramble about something
THEN you do the palm reading, maybe as she talks reach out and tuck her hair behind her ears if its dangling with a straight face as if that's how I roll. These are not ofcourse from the ACME manual of seduction it is just to show you that kino has to be escalated, it is like a meter from 1-100 you don't switch it on and off you rather go from 1 to 100%
Hope this helped out, and again you shouldn't wait for the second date, do all of that on day one, try to go as far as you can and keep on approaching you will get better as you do it more. Here are some articles I think you should give a read.
